应急广播系统多网络协同方案研究

Research on Multi-Network Coordination Scheme of Emergency Broadcasting System

地面数字电视(DTMB)具有覆盖范围广、信号分级可控、抗干扰能力强等优点。本文提出以DTMB传输为主,IP传输和FM无线覆盖等为辅的应急广播多网络协同方案,打造多网融合可视化应急广播系统,实现多业务、多平台,组建智能化统一管理平台,可以有效地推广、实施在应急广播项目中。

DTMB has the advantages of wide coverage,controllable signal classification,and strong anti-interference ability.This paper proposes a multi-network coordination scheme for emergency broadcasting with DTMB transmission as the main and supplemented by IP transmission and FM wireless coverage,so as to create a multi-network integrated visual emergency broadcasting system,realize multi services and multi platforms,and build an intelligent unified management platform,which can be effectively promoted and implemented in emergency broadcasting projects.
